' `To all fir/1 o/urz't may concern:

l ABedit known that I, Amiata PirrnsI-iN, a

'i subject okt'rthe King ot' Denmark, residing at .-lll'mthrop,y 1n the county of Suffolk and State of Massachusetts, have in'vented new and useful Imprcwements in Braidingiachines, owhiclitl-ie followmg is a specification.

l llhis invention relates to improvements in `braidingmachines and particularly to the il'otarytype ot' braiding machine.

' The objectyotitlns invention 1s to provide a braiding machine havii'ig' a series ot' strand guides adapted to beyrevolved about a center upon apsingle support and a series of thread- `mass carrieraadapted to be revolved about said centerupon a second support7 said tirst and 'second supports beingrotated simultaneously in opposite directions by a single rotatz' ing means, thus producing` a machine which may befoperated at a very high rate ot speed and which shall eliminate the friction and :wear usually;associated with a braiding ma- 'chine having/fl thread-mass farriers adapted to be independently revolved about a center byindividual driving means oi otherwise.

fr Another object of the invention to proliev supports for.` said thread-mass carriers upon the rotatable member by which said threademass carriers are revolved, said supports adapted `to be rotatedat a speed equal to the relative movement between said tirst and second i ientioned supports, whereby the 'strands which are carried-.by vsaid strand guides may be guided and fed beneath said threzul-mass"carriers, whenin t-heir lower- .v most positions., "without,injury thereto and f beiiigfcons-tiucted.

without danger ofcausing slack thread being t'orniedbetween said strand guides and the point on said machine at which the tubi-ic is afi-The invention consists in the combination and ai'iangen'ient of parts whereby the above objects and other objects hereinafter appearing maybe attained7 as set forth in the .'ll Afollowing4 specification and `particularly pointed out in the claims.

'eter-ring to thedrawings: Figure 1- is a connect-loin part elevation, of a rotary braiding machine embodying my invention, with but :two sets of, tbread-.n'iass carriers and strand guidesjshown therein. y Fig. Q is a detail plan i of a portion ofthe machine shown in FigMith parts broken away and shown in section to more clearly illustrate the inveiition. Fig. 3 is a detail section, part elevamounted by a bushingr 12 upon whiclrthe tubular fabric constructed b v said' machine is formed, and through which Asaid i'a'bfri'c is guided into said central supporting tube l1 and downwardly to the idler `13 mounted upon said central hub andlrom whiclrfsaid t'abric is drawn tothe take-up medhanisnh not shown in the drawings. .bsleeve int is rotatably mounted upon said `central supporting tube and has secured f thereon a beveled gear l5 adapted to rotate uponfthe upper face of the hub l0.` A, drivingfsha'ft' 1G is journaled to rotate in a 'bearing' 17 formed in the bracket 1S Asecured to a iiirg 19 which forms part of the rameeS, Said-Shaft lo has secured upon its outer end al driving pulley 2O and at its nneiwenda l'iinionllllls. which engages the beveled gear 1,5., ,.Uifioii' the sleeve lll, above aaidA geanl; is a rota? table strand guide support 22 rotatably mounted on said sleeve and provided with `gear teeth 23 adapted to engage said pinion 2l upon .the` opposite side o't' said` pinion relatively to its engagement with thegear .ln whereupon when said pinionis,rotated. said gear `and strand guide supprirty 22 are rotated simultaneously in opposite direef-r.- tions andy at a uni't'orni speed. l The strand guide support :22 provided with a cylindrical rini Q-l forming asup port 't'or a series of tbreadflnasses.Qyraid rini being' provided `with verticalslots through which the stands 2T, leading 'from said threadmasses are adapted toxfex tend to the bushing 12 where the tubular fabric is being' formed. .Located outside ot the. slots 2o are strand guidesftl;ilii'gg.V (i, through which said strands 27 are drawn and which are adapted to move said s riiids upi'vardly and downwardly within Said ing 12 extend through the eye 30, which islocated at the pivotal point ot the lever 29, thence along said leverthrough the guides 36 and 37 to the guides 2S located at the end of said lever from Which point, as hereinbefore del-scribed, they extend through the slots 26 to. said bushing 12. Fastened to the upper end of the sleeve 14 is a thread-mass carrier support 3 3 which @is adapted to be rotated with said sleeve 'and in the opposite direction'to that of the strand guide support 22, but atan equal rate of speed. A series of thread-mass carriers 39 are mounted upon said threadanass car- .rier support and revolved about the axis of said tube 1l, each being provided with a thread-Inass40v having a thread 41 leading therefrom through a guide 41 to the bushing 12. In the passage of the thread-mass carriers 39 about said center and relatively to said strand guides 28p, the strands'27 are moved from a position above to a position below said thread-mass carriers and must .therefore pass beneath said thread-mass carriers when in their lowermost positions. To facilitate the passage lof said thread beneath said carriers, I have provided means for feeding the saine therebeneath, which consist. of a series of radially disposed rotatable members 42, 42 arranged in pairs and each pair adapted to support a carrier, each of said members preferably consisting of a Shaft 43 having rolls 44 and 4.5 located ad- 45 jacent the inner and outer ends respectively of said shaft 43 and a pinion'46 secured adjacent to said inner roll 44. The rotatable members 42 are journaled at their opposite ends to rotate in bearings formed in the support 318, said members being preferably located in pairs Within segmental apeitures 47 which are formed by the radially disposed arms 48and the annular rim 49 connecting the outer ends of said arms and the annular rim 50, connecting t-he inner ends of said arms 48'and mountedupon a disk 51 secured Yonsaid sleeve 14. The outer bearings for i said rotatable members 42, hereinbetore mentioned, are formed in the rim 49: Whilesaid innerl bearings are formed in brackets 51 secured upon the rim 50.

' It Will be noted that the/rolls 45, located upon the outerends of the rotatable inembers .42, are `ot a greater diameter than the rolls 44 located adjacent to the inner ends Licentie of said members. This diilerence is made in order that said outer roll may have agreater surface speed than said inner roll so thatv the strand 2l' may be properly fed thereacross at a speed proportionate with the 'distance thereof from the center about which Said strand guides are revolved. The rotation of said members 42 is accomplished by means of a stationary beveled gear 52 formed in the shape ofa disk andwhich'is secured to said center supportiini` tube, thereby preventing vides a support for the strands 'adapted to guide the same in -a substantially straight line from said guide 23 to said bushing 12'1g at a time when said strand guide is in its lowerniost position, and preventing said strands from becoming entangled in the projecting parts of said thread-mass carrier support. 'Each ofthe tlireadqnass carriers 39 preferably embodies in its construct-ion a rectangular frame 54 adapted to rotatably support.t at its inner end;- a roller 55 and at its outer end a roller 56, said roller 55 being adapted to engage the adjacent rolls 44, 44 on the pair of rotatable members located in one of said segmental aperturesff' and the roller 5G is adapted to engagethe adjacent rollers 45 upon the outer ends of said rotatable members. It Will be seen that said carriers simply rest by their own weight upon the rolls 44 and and in order that they may be retained in such relation during the operation ot' said machine, I have provided means adapted to engagea flange 57 formed upon and extending downwardly trom the cylindrical portio of the support 227 said means preferably consisting of a pair ot rollers 58: 5S rotatably mounted upon the outer end ot each of said carriers and with their` centers located above said. rollers 56 and upon opposite sides of a' ventisei planecontaining the axes of both of Said;k

rollers and 5G. 'The placingof said rol`lers 53, 5S upon opposite sides of said plane is for the purpose or" preventingsaid carrier from tipping sidewise or iii-other Wordsto maintain the equilibrium of said Carrier while it is being revolved aboutthe centerv ot said carrier support. The flange 57 is also provided in its underface with an annular groove 59 into which said rollers 58 Vare adapted to project and thereby said oarriers are prevented from moving` radially upon their respective supports thus preventf lng said rollers 56 and 55 from becoming disengaged from the rolls 45 and 44 respectively.

The operation of the machine is as tollovvszvlhe thread-mass 40 is placed upon the spindle of the thread-mass carrier 39 and the thread drawn therefrom around the thread-mass carrier frame 54, through the guide 41 and'thence to the bushing 12 at the center of said machine Where it is connected with the threads leading'l from said series of thread-masses. The thread-mass carriers 39 are place'clfupontheir respective pairs or' rotatable members with the rollers 55 and 56 engaging the rollers 44 and 45 respectively,

and with the rollers 58 engaging the ,groove 59inthe flange 57,the strands are then drawn from the thread-masses 'through the thread guides in their respective levers to the thread guides 28, thence through the slots 26 and to the center bushing 12. kUpon the rotation of the shaft 16 through the power transmitting instrumentalities, the pinion 21 is rotated which in turn rotates the ,gear in one direction, and the gear formed by the teeth 23 upon the support QQ, simultaneously in opposite directions. The lrear 15 through the sleeve 14 imparts a rotatory motion to the thread-mass support 38 inthe opposite direotion to the strand carrier 2Q and by said rotation the shafts 42 Will be rotated through their respective pinions 46 engaging the ear 52. During the rotation of the support 22 the levers 29 are oscillated upon the rackets by the roll 32 engaging the cam oove 33 which actuate the strand guides ;-28,7Whereby said strands 27 are moved above andjbeloiv the thread-masses and while said'strands 27 are below said thread-masses 4,0I they will be fed beneath the same by the rotatory movement of said rods 44 and 45 in engagement with rolls and 56 respectively.

The foregoing detailed description has* been given for the purpose of elucidating the invention in its preferred embodiment and no undue limitations should be understood therefrom, but the claims should be construed as broadly as permissible in view of the prior art.
